3. Functional description
EKS PROFINET devices are read/write systems with electronics for the inductive bidirectional interface to the transponder
and the interface electronics.
The system is connected via the integrated PROFINET interface, which is designed as an RJ45 socket. A separate switch
may be required for the PROFINET connection. The EKS does not have an integrated switch.
The current state of the Electronic-Key adapter is displayed using a 3-color LED.
The Electronic-Key is placed on the Electronic-Key adapter for operation. The power supply for the transponder and the data
are transferred between the Electronic-Key adapter and the Electronic-Key without using any contacts.

PROFINET Description Function
Byte 1
Receive data Max. 124 bytes user data from the Electronic-Key plus 3 bytes reserve. If fewer bytes of data were
selected during conguration, these are lled with 0hex.

PROFINET Description Function
Byte 1 Start address Denes rst byte in the memory in the Electronic-Key that is written on setting bit no. 0 in the
command byte. Start address of user data: byte no. 0, 4, 8 … 112.
Byte 2 Number of bytes Denes the number of bytes in the memory in the Electronic-Key that are written on setting bit no.
0 in the command byte. Number of bytes of user data: 4, 8, 12 … 116 bytes.
Byte 3 Not used
Byte 4
Transmit data If bit no. 0 in the command byte is set to 1, the content of these bytes is written to the Electronic-Key
starting from the start address dened.

Byte 127
Not used
TIP!
You will nd further information in the manual.
NOTE!
On the Electronic-Key read/write with 116 bytes freely programmable, the memory is organized in
4-byte blocks. This means the start address for writing must be given in the range byte number 0 to
byte number 112, always in 4-byte steps (byte number 0, 4, 8 ... 112). Also a multiple of 4-byte sized
blocks must always be written (4, 8, 12 ... 116 bytes).
During reading it is possible to access the memory byte-by-byte without the above-mentioned restric-
tion for writing.

5. Installing the GSD le
You will require the corresponding GSD le in the GSDML format to integrate the EKS into TwinCAT 3, depending on the
design of the EKS:
Design Related GSD le
compact
(Order No. 106305/106306) GSDML-V2.31-Euchner-EKS_3.x.x_109539-YYYYMMDD.xml
modular
(Order No. 122352/122353) GSDML-V2.31-EUCHNER-EKS_PN_modular_126145-YYYYMMDD.xml
You will nd the GSD les in the download area at www.euchner.com. Always use the latest GSD le.
Please proceed as follows to integrate the GSD le in TwinCAT 3:
Open the path as shown in Figure 1 and then add the unpacked GSDML and bitmap le.

7. Conguring and setting the parameters of the EKS with PROFINET interface
7.1. Conguring the PROFINET network
Add the PROFINET network as follows:
1. In Solution Explorer click I/O, right-click Devices and choose Scan.
Figure 3: Adding PROFINET network
NOTE!
To undertake scans the TwinCAT must be in the Cong Mode.
2. Select the PROFINET controller and accept using OK.
